Startup Procedure; Fire Alarm Test; Troubleshooting - Det-Tronics X5200 Instructions Manual

STaRTUP PROCEDURE

When installation of the equipment is complete, perform
the "Fire Alarm Test" below.
Allow 20 to 30 minutes for the detector's heated optics to
reach equilibrium.

FIRE ALARM tEst

1. Disable any extinguishing equipment that is
connected to the system.
2. Apply input power to the system.
3. Initiate an o i test. (See "Magnetic o i / Manual o i "
under Optical Integrity in the Description section of
this manual.
4. Repeat this test for all detectors in the system. If
a unit fails the test, refer to the "Troubleshooting"
section.
5. Verify that all detectors in the system are properly
aimed at the area to be protected. (The Det-Tronics
Q1201C Laser Aimer is recommended for this
purpose.)
6. Enable extinguishing equipment when the test is
complete.

WarnIng
The sensor module ("front" half of the detector)
contains no user serviceable components
and should never be opened. The terminal
compartment is the only part of the enclosure that
should be opened by the user in the field.
1. Disable any extinguishing equipment that is
connected to the unit.
2. Inspect the viewing windows for contamination and
clean as necessary. (Refer to the "Maintenance"
section for complete information regarding cleaning
of the detector viewing windows.)
3. Check input power to the unit.
4. If the fire system has a logging function, check the
fire panel log for output status information. See Table
4 for information regarding 0 to 20 mA output.

1 If fault continues, return device to factory for repair.
2 See "Maintenance" section for cleaning procedure.
5. Turn off the input power to the detector and check all
wiring for continuity. Important: Disconnect wiring
at the detector before checking system wiring for
continuity.
6. If all wiring checks out and cleaning of the
window did not correct the fault condition, check
for high levels of background UV or IR radiation
by covering the detector with the factory supplied
cover or aluminum foil. If the fault condition clears,
extreme background UV or IR radiation is present.
Re-adjust the view of the detector away from the UV
or IR source or relocate the detector.
If none of these actions corrects the problem, return the
detector to the factory for repair.
It is highly recommended that a complete spare
be kept on hand for field replacement to ensure
continuous protection.
